Design and Simulation of Efficient DC-DC Converter Topology for a Solar PV Modular Integrated Converter System

Abstract: Modulated Integrated Converter systems are considered to be the new and global turning point in the field of Solar PV systems. These converters are highly recognised for its modular size and compact nature and they are supposed to be attached directly with each PV module and since one PV module is having the power rating of a few watts ranging from 0-500Ws, the design rating would be in the same range and thus the most vital condition in such a design is efficiency under these relatively low loads. In this paper an isolated interleaved boost converter topology is considered in the DC-DC section and which is designed and simulated for a specific power rating (250W) and the efficiency is analysed with varying load conditions and compared with the target efficiency of the system.
